GEO. W. HATHAWAY, OF TIOGA, PENNSYLVANIA.

FEED-CUTTER.

Specification of Letters Patent No. 30,817, dated December 4, 1860.

To aZZ whom t may concern:

Be it known that I, G. WV. HATHAWAY, of Tioga, in the county of Tiogaand State of Pennsylvania, have invented a new and useful Improvement inFeed-Cutters; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing, making a part of this specification, in which-Figure l is a side elevation of the machine. Fig. 2 is an end view ofthe same.

Similar letters of reference indicate corg responding parts in bothfigures.

To enable those skilled in the art to make and use my invention I willproceed to de scribe its construction and operation, with reference tothe drawing'.

The several letters A, represent the frame.

E, is the driving shaft, y, the crank, and B, the balance wheel, to thearms of which the knives Zo, and Zc, are attached the points beingpivoted at o, and the heel being attached to the movable block u', whichslides in the slot u. The knives should be made as shown at 7:', theheel being much broader than the point, and as the wheel B, revolves,the back of the knives is drawn (one after another) under the roller ZL,which causes the heel or broad end to swing down or concentric from theposition shown by the red lines in Fig. 2, thereby producing asecondary, or compound, movement to their cutting edge. The said rollerZL, is hung to the arch g, one end of which is pivoted to the frame atc", and the other end is made adjustable by means of the set screw c',which passes through the slot o, and into the frame.

The concentric throw of the heel of the knives may be increased bydropping the end of the arch g, at z'.

I use the ordinary feed rollers p, the axis of the lower one beingfixed, and the upper one is allowed to move vertically in the slots c,of the caps C, in adjusting itself to the inequalities of the materialwhich is being cut, by means of the elastic driving bands e, at eachend, which run in the grooves of the pulleys p, and drive the said upperroller. The ratchet wheel o, of the lower roller 11, is operated by thepawl Z, which is pivoted in the box of the head m, of the rock shaft f,on the opposite end of which is placed the arm d, and as the wheel B,revolves, the pins a, press the end of the arm Z down which rocks theshaft f, and the pawl Z, is moved upward, and turns the rollers r, whichare prevented from turning back, by the spring latch s, which is Xed tothe side of the frame A.

The pawl Z, is kept in gear with the ratchet wheel o, by the spring s,one end of -which is Xed to the head m, and the other presses againstthe spur shown by the dotted lines at oc, in Fig. l.

It will be seen that by bearing the arm CZ, down, the spring s, iscompressed and its inclination to recover its natural position, togetherwith the eXtra weight on that side of the rock shaft f, causes the pawlZ, to drop down the instant the arm (Z, is relieved by the passing pina..

The feed of the rollers fr, is regulated by means of the cam n, whichwhen turned up as seen in Fig. l, gives the longest feed and to decreasethe length it should be turned down, which will give the shortest feed,and by turning' its eccentric side horizontal with its axis, it gives amedium length to the feed.

The arm CZ, is so connected with the rock shaft f, as to be turned upwithout turning the said shaft by means of which the parts would not bebroken if the wheel should happen to turn backward. By removing thecrank y, and applying a belt to the balance wheel B, the machine may bedriven by a steam engine or other motor.

What I claim as new and desire to secure by Letters Patent, is-

1. The combination in the manner specified, of the roller n, andadjustable arch g, with the knives Zo, arranged and operated as setforth.

2. The combination of the rock shaft f, its arm (Z, head m, spring s,and pawl Z, with the cam n, they all being constructed, arranged andoperating in the manner and for the purpose specified.
